SVERRE JOHNSEN, OF BERGEDORF, NEAR HAMBURG, GERMANY.

EXPENSE-3E GISTER.

Application filed November 1, 1906.

To all whom it may concern:

Be it known that I, SVERRE Jonivsnn, a subject of the Emperor ofGermany, and aresident of Bergedorf, near Hamburg, Germany, haveinvented certain new and useful Improvements in Expense-Registers, ofwhich the following is a specification.

This invention has reference to a novel expense register.

It is the special object of my invention to produce such a device forregistering daily expenses, adding same up, and indicating the remainingcash on hand. Each expenditure is registered in a simple andinconspicuous manner. The single items are simultaneously added up and;the remaining cash is indicated. By observing the remaining cash one iscautioned against careless expense and learns to economize. Y

The invention is illustrated in the accompanying drawing in which Figure1 represents in front view an expense register which embodies indesirable form the present improvements. Fig. 2

shows same with the glass and dial removed.

Fig. 3 illustrates same on an enlarged scale in vertical section at aright angle to Fig. 2. Fig. 4. shows a modified form of the device inrear view with the rear cover removed which is adapted to registerlarger amounts. Fig. 5 is a rear view of the mechanism of the modifiedform shown in Fig. 4 with the rear cover and rear dial plate removed.Fig. 6 is a vertical cross section at right angles to Fig. 5 on anenlarged scale. Fig. 7 illus- Fi 8 shows in vertical section the topportidli of the device shown in Fig. 7 on an enlarged scale and at aright angle thereto.

The device is preferably made in the form of a watch. It is providedwith four hands a, a 6, and c, which move on a dial g. The hands aremoved by means of a stem winder knob d in the, following manner: Theknob (Z is in rigid connection with a bevel gear 6. This gear engageswith a bevel gear f which is mounted on the spindle of the hand a, seeFig. 3. To the spindle of the hand ais also rigidly connected a pawl 3;adapted to engage the lateral teeth of a wheel to which fits loosely onthe spindle of the hand a and has both spur and lateral teeth. The pawlx will move the wheel w only when the hand a and said pawl turn in thedirection of making an addition. By means of suitable intermediategearing y, see Fig. 2, the rotation Specification of LettersPatent.

of the wheel w, when efi'ected in the direction of making addition only,is transmitted to a spur gear 2 which will turn the hand (1 each time toadd the expended sum. By turning the knob (Z backward, the hand a isturned to its zero position after one expenditure has been registeredwithout aiiecting the hand a A suitable stop 30, say a ilat spring, maybe provided which will prevent the hand a from being moved backwardbeyond the Zero position, but will not offer any resistance to the handwhen moved forward.

A wheel a on the spindle of the hand (1- engages a gear wheel n. Thegear wheel 17, and a gear wheel n are rigidly mounted on the s lnd'le n.The gear wheel engages a t ird gear wheel 0 which is loosely mounted onthe spindle of the hand 6. The gear wheel 0 is moved by the operation ofthe spindle of the hand a through wheel a, the gears 11. and n at aratio of, say 1 to 50 thus proplortionally transmitting the movement oft e spindle oi the hand a to the spindle ol the hand I). At the showngraduation oi the dial for the hands a and a in hundred parts and thatof the hand b in fifty parts the hand a will indicate the cents(plennige) and the handb the dollars (mark) oi the sum exended when thehand a after each operation as been returned to Zero. At ratio of one toone the gear wheel 0 drives a gear wheel 1 which is mounted on thespindle of the hand 0 so that when the gear 1" and the hand 0 arecoupled, the hand 0 will move backward over a dial and perform asubtractive operation. It now the hand a is set to indicate the sum onhand and the hand a moved by means of the knob d after each expendituresuch a distance on its scale as corresponds to the amount expended, thehand 0 will indicate the cash remaining on hand and a correct and clearreading of the expenses is afforded, in dicated by the hand I) indollars (mark) and by the hand a in cents (pi'ennige). By turning theknob the expenditure only can be registered, a turning of the knob inthe opposite direction remains without eflect owing to the action of thepawl a: and the gear mechanism. Sometimes, however, it is cl importanceto move the hand 0 without moving the mechanism, when for instance thecash on hand is to be increased. In order to do this and also eflect theadjustment for expenditure without unnecessary and time wasting turning01' the knob (Z, the couplings lll) shown in Fig. 3 on an enlarged scaleare provided. By means of said couplings the gears 0 and 7" may beconnected with or disconnected from the respective spindles as may berequired. Such friction couplings between a hand and a driving wheel arealready known to the art. The present invention consists in theregistering mechanism of single expenditures, the adding of same, andthe registering of the remaining cash on hand.

' The coupling of the wheel 0 consists essentially of the device shownin the drawing. A split cone g which is connected with the press knob iis forced into the conical bore of the wheel 0 by a spring h. The splitcone g having a cylindrical bore inside grips the spindle of the hand I)so tightly that the wheel 0 when turned in the direction of the arrowshown on Fig. 1 will move the hand I) steadily and accurately wherebythe spring h is tightened, it being secured with one end to the dial orsome other stationary part of the case and with the other end to thespindle of the hand Z). However, if the knob i is pressed, the cone Qwill leave the conical bore of the gear 0 and the said cone 9 releasesthe spindle of the hand at and the spindle and hand will be returnedinto the zero position of the hand I) by action of the spring h. Stops sand t are provided to prevent that the hand be returned farther than tothe zero po sition.

The gearing mechanism and hand 0 remain stationary owing to the frictionbetween the wheels. The hand 0 also may be adjusted independently by aknob is after the coupling g on the spindle of the hand I) has beendisconnected. In order to move the hand 0 independently, it is necessaryto press the knob i for disconnecting the coupling q and at the sametime turn the knob 7c. It is also possible to avoid this operation andto adjust the hand 0 only by pressing and turning the knob is. While theknobs 7c and i are suitably arranged as shown underneath the cover ofthe case, the knob d is made to pro ject from same.

In the device illustrated in Fig. 1 the dials are graduated for cash andexpenditures up to an amount of fifty dollars (mark). In order to renderthe instrument useful for business purposes and large amounts, thescales on the dials shown in Fig. 4 are graduated up to a thousanddollars (mark); such dials are suitably arranged on the back and underthe cover of the device because they run up to a thousand dollars andtherefore are rarely used. Furthermore the dials and the mechanismpertaining thereto would crowd the front portion of the watch too much.

A modification of such character is shown in Figs. 4, 5, and 6. Themechanism of this device is the same as above described, but iscomplemented by additional parts.

der the wheel 1" of the first described device is located a wheel 15which engages with an intermediate gear 16 driving a gear wheel 17 onthe spindle of the hand 20 which indicates the remaining cash. By theintermediate gear wheel 18 a gear 19 is driven which is mounted on thespindle of the hand 21 which indicates the ex enditure made. In order torender it possib e to move those hands independently as may be requiredwhen the cash on hand is to be increased, the wheels 17 and 19 areconnected to their spindles by means of couplin s, which are to bedisengaged by pressing the knobs 22 and 23 shown in Fig. 6.

A further improvement of the above invention relates to its expenditureregistering device and consists in turning the count ing mechanismautomatically to the zero position. This improvement differs from thoseheretofore known in which the hands or dials were turned by means ofsprings into their initial position. In the present device an adjustingknob is displaced by pulling whereby certain gears are disconnected andthe main and hand spindles being under spring action are returned intotheir initial position. The device for carrying this into practice isshown in Figs. 7 and 8.

On the driving spindle 1 a spring 3 is provided which continuouslyresse's the bevel Wheel 4 against the bevel wheel 5 which latter ismounted on tne spindle 2. At the end of the s )indle 2 a ratched wheel 6is provided whic is secured to a plate 7. On this plate 7 a disk 8 isloosely arranged. This disk has on its inner side a pawl 9 which engageswith the teeth of the ratched wheel 6. Around the disk 8 is arranged aspiral spring 10 which is secured with one end to said disk and with theother to a dog 11 on the spindle 2. If now the spindle 2 is turnedforward by means of the knob 31 the spring 10 is tightened because it issecured with one end to the dog 11 and held with the other end by thepawl 9 catching in the ratched wheel 6 which is rigidly secured to theplate 7 of the case. The pawl 9 serves the purpose of avoiding an unduestrain on the spring 10 and is indirectly connected with this spring bythe disk 8. The spring thus tightened follows the rotation of the disk6. If now a slight pull is exerted on the knob 31 the spindle 2 and withit the coupling of the bevel wheels 4, 5 are released and the spindle 2will instantly turnbackward until it, is stopped by the hand 32 whichstrikes against the stop 33 provided on the zero point. It will furtherbe found of advantage if each complete revolution of the hand 32equaling one dollar (mark) is made audible. This is of value when theeX- pended amounts run into high figures. A device of this kind rendersit unnecessary to pay close attention to the dial which becomes annoyingby the repeated turning of the knob 31 when a number of dollars or marksare at once expended. A steel lip 13 is secured to the top cover whichwill give an audible sound each time an arm 14 strikes against it.

Having thus described my invention I claim as new and desire to secureby Letters Patent:
